VLSI (Very Large-Scale Integration) is a crucial aspect of semiconductor design, enabling the integration of millions of transistors on a single chip. As technology advances, the complexity of chip design increases, requiring rigorous verification processes to ensure functionality and reliability. Physical verification in VLSI plays a vital role in ensuring that a design meets all fabrication requirements before proceeding to manufacturing. It involves checking layout rules, connectivity, and design constraints to prevent costly errors. Without proper verification, even minor design flaws can lead to significant issues in chip performance, yield, and overall production costs. This verification process includes Design Rule Checking (DRC), Layout versus Schematic (LVS), and Electrical Rule Checking (ERC), all of which contribute to the integrity of the final product. The need for physical verification has grown significantly as technology nodes shrink, making it an essential step in semiconductor design.
